Hospitality Property Energy Audit
Comprehensive energy audit for a two-tower mixed-use hospitality property with 362 serviced units. The project identified high-impact operational improvements and equipment upgrades to reduce energy use, improve indoor comfort, and align with sustainability goals. The recommended measures are expected to cut energy consumption by 41.9% to 53.5%, lowering the Energy Use Intensity (EUI) from 141.4 kWh/m²/year to 74.0 kWh/m²/year and achieving significant carbon reduction.
Detailed Assessment
- Full evaluation of chiller plants, AHUs, ventilation systems, and control strategies.
- Review of lighting, hot water systems, and electrical load control in guest rooms and common areas.
- Identification of water conservation opportunities to reduce energy and water demand.
Performance Evaluation
- Chiller plant optimization and control upgrades.
- Integration of guest room key card systems with thermostats for occupancy-based cooling.
- Automated economy mode control for corridor fan coil units.
- Replacement of outdated AHUs with energy-efficient models equipped with advanced controls.
- Installation of VFDs on kitchen exhaust fans and hot water pumps.
- Water-saving fixtures for faucets and showers.
- Motion sensor installation in corridors and lighting optimization in parking areas.
- Electrical circuit optimization in guest rooms to disconnect non-essential loads when unoccupied.
- Planning for future heat pump upgrades with modulating compressors for hot water systems.
Diagnostic Testing
- Verification of control sequences for optimized chiller and ventilation operation.
- Indoor environmental quality checks following fresh air system retrofits.
- Continuous monitoring integration to track performance and detect inefficiencies.
Maintenance Review
- Preventive maintenance planning for chillers, AHUs, and VFD systems.
- Training of operational staff on optimized control systems.
- Scheduled retrocommissioning every three years to maintain efficiency gains.
System Optimization
- Occupancy-based cooling strategies for guest rooms and common areas.
- Advanced control logic for AHUs and fresh air systems.
- Load reduction through façade improvements and air infiltration control.
Efficiency Improvement
- Estimated Annual Energy Savings: Up to 53.5%.
- Carbon Reduction: Significant reduction in operational footprint through combined HVAC, lighting, and water system upgrades.
Result: A comprehensive and phased improvement plan enabling substantial energy and carbon reductions while enhancing guest comfort, operational reliability, and indoor air quality in a high-profile hospitality property.
